AUDIO SIGNAL CABLES
When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the amplifier,
the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. We
recommend a separated installation, e.g. routing the power cable through the cable channel on the left side
and the audio cables through the cable channel of the vehicle on the right side or vice versa. This prevents
interferences due to crosstalk into the audio signal.
OPERATING ELEMENTS
INPUT SENSITIVITY (FRONT, REAR & SUB)
Turn the LEVEL INPUT (Fig. 1.3, 1.6 or 1.15) controller of the amplifier to the MIN position. Then turn the vol-
ume controller of the head unit to 80 - 90% of its full setting. Now turn LEVEL INPUT clockwise until you hear
some distortion. Then turn back the LEVEL INPUT slightly until you hear a cleaner sound.
VARIABLE HIGH PASS FILTER (FRONT & REAR)
Set the desired crossover frequency on the HIGH PASS controller (Fig. 1.3 or 1.8). Thus to that only the fre-
quencies above the chosen crossover frequency will be amplified. This effectively minimizes distortions and
overloads at lower frequencies. A good point to start is at 125 Hz.
VARIABLE LOW PASS FILTER (SUB)
Set the desired crossover frequency by using the controller (Fig. 1.13). Thus to that only the frequencies below
the chosen crossover frequency will be amplified and the subwoofer plays more precise and efficient. A good
point to start is at 125 Hz.
VARIABLE BASS BOOST (SUB)
With the controller BASS BOOST (Fig. 1.12) you are able to adjust the bass level from 0 - 12 dB.
Attention: Use the controller BASS BOOST wisely!
VARIABLE SUBSONIC FILTER (SUB)
With the SUB SONIC controller (Fig. 1.14) you can adjust the lower crossover frequency, to filter the very low
frequencies to relieve the subwoofer or to generate a bandpass signal. If you don't want to use this function,
turn the controller (Fig. 1.14) to the very left to the 10 Hz position.
NOTE: The adjusted value of the SUB SONIC (Fig. 1.14) should not be higher than the adjusted value of the
LOW PASS controller (Fig. 1.13). Otherwise no sound will be audible.
PHASE SHIFT CONTROLLER (SUB)
The PHASE SHIFT controller (Fig. 1,11) allows to adjust the phase between 0° and 180° to match the output
signal with the vehicle's interior acoustic.
BASS LEVEL REMOTE CONTROLLER (SUB)
With the included bass level cable remote controller (Fig. 1.16) you are able to adjust the bass level e.g. out
of the driver's seat.
PROTECTION CIRCUIT
The POWER LED (Fig. 1.9) lights up green, if the amplifier is in operation.
The PROTECTION LED (Fig. 1.9) lights up red, when the amplifier is overheated, or a short circuit occurs resp.
a too low impedance load is connected to the speaker outputs. If this events, the internal built-in protection
circuit shuts down the amplifier automatically. The amplifier should work again properly after you have solved
the problems.
